The Last Man in the Universe

Alexander reached the long building, he got off the rail track, and climbed the platform where the building was. Exploring the outside of the building, from the back to the front.

"Denia!" he called out to his lover with such great worry in him. "Denia, where are you?! Charlie…!"

He didn't see or hear any noises and continued to move cautiously toward the front.

Alexander gasped slightly because he stepped on a puddle of thick liquid in front of the half-opened entrance. The gloom made him have to be more careful.

When he was about to try to enter, he nudged Hunter's corpse who was sitting on the right side of the entrance. The corpse shifted and fell to the floor.

Alexander gasped and spontaneously jumped to the left. But the figure didn't move at all, he gulped. Don't tell me that the thick liquid I stepped on just now was a pool of blood, he thought.

Then, whose corpse is this?

Thank You, Buddy!
